Lowell Corporation Ratcheting Crank Handles, Model 101

For easier, more efficient machinery adjustment
Our ratcheting crank handles come with fixed or rotating metal or plastic knobs for extra durability. Lowell’s bolt-thru design allows bolts to pass entirely through the arm head so that nuts can be secured on any threaded length. Performs many adjustments including cross feed, rise and fall, gib and quill, positioning screw, or clamping. Reversing control located in the head to reverse the action safely and easily. Available in square, hex, bore or custom openings.
